[XOM-interest] Birds of a feather invitation

Next week on Wednesday evening, there will be a XOM Birds of a Feather session at Software Development 2003 West. The gathering takes place at the pool of the Westin Santa Clara in the heart of Silicon Valley. <http://www.thewestinsantaclara.com/home.htm> Beverages and munchies will be available. Officially this event is for conference attendees. Unofficially, since I'm paying for the beer, I figure I can invite whomever I want, and all members of this mailing list should consider themselves invited. :-)

I don't know what we'll be talking about. It depends on who shows up, and what they're interested in. This past week in London the hot topic was whether XOM should use interfaces or classes. Personally, I'm very committed to classes, so I don't see any realistic chance of that changing, but a possible fork was discussed. :-)

I found a behavior with ParentNode.hasChildren() that surprised me. Not sure
if this is a bug or designed behavior but when I try the following code
snippet....

Element element = new Element("test")
Attribute attribute = new Attribute("name", "value");
element.addAttribute(attribute);
boolean gotKids = element.hasChildren();

....gotKids evaluates to false. The documentation says that "hasChildren"
returns true if the node has child nodes. Since Attribute is a node shouldn't gotKids
evaluate to true?

P.S. I'm not on the XOM mailing list so please direct a copy of any replies to brian AT mbari.org <mailto:brian AT mbari.org>

I've posted a new version of the "What's Wrong with XML APIs (and how to fix them)" slides on the web site:

http://www.cafeconleche.org/XOM/whatswrong/

This mostly fixes various anachronisms I noticed while presenting XOM to the UKUUG and XML UK user groups in London this past week. It also improves the formatting and adds a couple of bullet points here and there.

I'm increasingly unimpressed with the OpenOffice Impress program I use for this presentation. PowerPoint it's not. Before I give this talk again, I really have to port these notes to XML like the rest of my classes.

No, an attribute is a node but it is not a child so this is not a bug. Attributes are on a different axis in XPath terms. Yes, this is a little weird, and it threw me when I first started working with XPath.

P.S. I'm not on the XOM mailing list so please direct a copy of any replies to <mailto:brian AT mbari.org>brian AT mbari.org

Interesting. In that case, you shouldn't have been able to post. I wonder how it got through? That may explain a little of the spam on the list lately.

guys, I know that this may sound hard to believe, but they buglarized
my house and among other things they took a sack with the copy
of the linux journal which contained the XOM article I had purchased when I
was in the US.

Since I have failed to find the magazine again here in europe so far,
can anyone tell me where I can find the article or, at least, the source code
in the article? I am particularly interested in the bit
that does the parsing, since the tutorial on the cafeconleche site
fails to give a complete example and I understand the alternative is
to study the SAX/Xerces stuff before I get even the simple things done.

Thank you

Luca

PS: I am evaluating using XOM for handling the XML parsing
part of another open source project I am managing.
The guy who did the XML part used JAXB, but I am not convinced of his
choice. Elliote, are you interested in hearing about that project just to see if there
are any possible synergies?
in the affirmative case, do you want me to take the conversation off-line or
should I post here?
